4. Technical Description:
Construction of the canopy:
The canopy of the Garuda is made of Porcher Marine Skytex Ripstop Nylon-fabric Art. 9017 E77a and Skysport
D70. In this synthetic fabric a reinforced thread-net is woven in, which stops the fabric from further tearing and
is increasing the firmness at the seams. The coating makes the fabric water-repellent, UV-stabile and air-
impermeable.
The Garuda consists of 52 cells. The wingtip (stabilisator) is pulled downwards and is intergrated in the
canopy.
The aeration of the canopy is done through the openings on the bottom side of the profile-nose. The lateral
aeration is done through exactly dimensioned openings (cross ports) in the profile-gill.
Every carrying profile-gill is suspended from 4 Line-attachement-points, which are reinforced in the profile
itself.
Between the single groups of main lines are taut ribbons sewn in, which are regulating the tension of the sail.
At the profile´s nose reinforcements are sewn in, which gives the canopy more stability.
On the entry- and trailing-edge of the canopy a special ribon with low elongation is sewn in, which offers a
cunning, by our design-software calculated, tension-distribution along the canopy.
Suspension-system/Line-system:
The lines of the Garuda consist of polyester-covered HMA Aramid and polyester-covered and uncovered PES /
Dyneema, depending on where the line is placed. The strengths of each line depend also on the place where the
line is built-in, and are varying between 100
The lines are differing depending where they are built-in like follows: Top-lines (up at the canopy), middle-
section-lines (between main- and top-lines), main-lines (down at the riser), stabilisator-lines (at the wingtip)
and brake-lines (up at the trailing-edge) and main-brake-lines (at the brake-handle).
The lines are differentiated in A / B / C / D level and the brake.
Within the levels always 2 top-lines are combined to one middle-section-line. On the main-line level always 2
middle-section-lines are combined to overall 6 main-lines per level, which are mounted to the maillon rapides
shackles at the corresponding riser.
The stabilisator-lines are mounted to the B-riser together with the B-level.
The brake- or steering-lines are combined to the main-brake-line in the same way..
The lines of each level are coloured differently to make it easier to differentiate and check it.
The complete riser of the Garuda consists of 5 risers.
The A-riser is splitted in a main(A)-riser and a sub(A´)-riser (also called outer- or baby A´riser). On the A-riser
2 main-lines are attached, on the A´one main-line is attached.
On the B-riser per side 3 B-main-lines plus one stabilisator-line are attched.
The C-riser and D-riser take in always 3 main-lines.
The main-brake-line is running through a pulley at the D-riser to the brake-handle.
The maillon rapide shackles at the risers are made of stainless steel and are secured with an plastic-inlay
against unintentional opening and against a slipping of the lines.
The complete geometry of the lines is shown on the single line plan, which you find a few pages behind..
Speed-system:
The Garuda has got a speed-system at the riser which is activated with the legs of the pilot. If the speed-system
is released it goes back to the original position automatically. The riser has no trimmer which can be fixed
The speed-system shortens the A and B risers and reduces the angel of attack of the canopy.
In normal flight all risers have the same length (54,5cm with the shackles). If the speed-system is activated the
A-risers gets up to 14,5cm, the B-risers up to 13,5cm, the C-risers up to 6,5 shorter. The length of the D-riser
does not change.
and 240 daN.
Functionality and handling:
Before take-off the Brummel-hooks of the harness´speed-bar are connected to the Brummel-hooks of the
speed-system at the risers. You have to take care that the line of the speed-bar is running free.
Before the first use of the speed-system you have to adjust the length of the speed-bar´s lines correctly. The
best way to do this is in a simulator. The legth is set correctly if the lines still have some free space and are not yet
under traction if the speed-bar is not pushed.
By pushing the speed-bar with his legs the pilot shortens the A, B and C risers with the pulleys at the riser. This
pulleys are reducing the necessary forces.
